Exam 15: River Systems and Landforms

The suspended load of a stream is the coarser materials that are dragged along the stream bed.

Which of the following is correct of floodplains?

Maximum velocity in a meandering stream is

As they migrate, meandering streams erode their out outside banks, often forming a narrow neck of land that eventually erodes through and forms a ________ and the stream becomes ________.

Base level refers to the average stream depth immediately following a normal precipitation event.

Of the world's largest rivers, which has the greatest discharge?

Which of the following is likely to occur if the gradient of a stream increases? (Assume that the discharge and sediment load remain unchanged.)

Which of the following landforms is incorrectly matched with a drainage pattern?

A 50-year flood has an annual exceedance probability of

A basin in which water leaves via evapotranspiration or subsurface gravitational flow instead of reaching the ocean is said to have

Only larger rivers and streams have their own drainage basins.

If the load exceeds a stream's capacity, sediment accumulates in the bed in a process called

Describe the formation of deltas.

Structural domes with concentric patterns of rock strata guide stream courses to form this drainage pattern.

The statistical rating of flood discharge is based on

This drainage pattern is associated with steep slopes.

The sediment load consisting of coarse material too large to remain in suspension, moving along the channel bottom via traction and saltation is the

Channels with gradual slopes often develop a sinuous form called a ________ pattern.

In a straight channel, the greatest flow velocities are found along the bottom in the middle of the stream.

If a stream originates in a humid region, but subsequently flows through an arid region, discharge is likely highest
